The present work speaks about experimental evaluation of Mechanical and Fracture properties and simulation studies (by FEM and XFEM) to analyse fracture behaviour of ultra fine grained 7075 Al alloy produced by cryorolling technique. The precipitation hardenable Al 7075 alloy (Al-Mg-Zn-Cu) plates were solutionised and then cryorolling (rolling at liquid nitrogen temperature) done to achieve different thickness reductions (40%, 70% and 90%). It was observed that at 70% thickness reduction fully formed UFG (Ultra Fine Grained) structure produced for the 7075 alloy. Some of the specimens were...
